Description

When making a new request in the Continue Extension, the code block content does not display correctly. It doesn't show the code, with all text displayed in the same color as the background, regardless of whether it's light or dark theme.

On other themes, it uses a single color to display all code.

To reproduce

1. Toggle theme: Use Ctrl+K Ctrl+T and switch to Dark High Contrast.
2. Generate code: Use Ctrl+Shift+L and try any prompt for code generation. Observe how the code block content displays.
3. Re-submit request: Select the last request block and submit it again.
4. Code block should display correctly: The code block content should now display correctly after re-submitting the request.
